Nvidia Ampere A100 GPU scores 446 points in OctaneBench

[HEXUS]

Indicates it is nearly 50 per cent faster than the fastest GeForce GPU in this rendering app.

But isn't this the absolute cream of the crop top end silicon for the top inferencing cards whereas what will realistically be available is far smaller and lower performance. That 40GB of HBM2e is also going to be literally bank breaking.

What does it says?
I have no idea what the benchmark measures, and how it would translate to normal gaming performance. Will that mean at least 4k@60Hz on ultra with 99,9% time or maybe close to 4k@120 ?
If anything less, then it is failure, no matter the numbers in benchmark.

AFAICT it measures raytracing, i would say realtime raytacing but IMO whether something is realtime sort of depends on the detail level and frame rates, technically my old i7 920 could do realtime raytracing if you'd be happy with 1 frame per day.

would you rather see the intel way of 5% gain in generation?

Actually, Octane renderer is an unbiased pathtracing renderer.

With RTX disabled (Octane 4 - and therefore Octanebench 4 doesn't support RTX - the 2020 version does), the benchmarks are basically about pure FP32 grunt.

So it doesn't really equate to gaming, and with RTX disabled, not realtime raytracing either. Otoy does have tech for that, but Octane is more about 'final' quality for TV and film etc rather than realtime, currently.

With RTX enabled, the Turing gen was getting 1.5-4x speed improvement, especially in scenes with more raytracing of course. So, for people doing CGI, it will be also very interesting to see what the Ampere RTX speedup is.

So from a laymans POV is RTX not doing unbiased pathtracing renderering? If so what's the difference difference between that and RTX?

I'm talking as someone who didn't even know there were different types of raytracing until 5 seconds ago so you may have to dumb it down, really dumb it down.

This guy gives a good explanation of the render methods, if a little slow, but his 3D illstrations show what's what. It was created before Octane 4 came out, but the info is solid.

AMD's software ray tracing could easily give 60fps 2 yrs ago.
Hardware ray tracing is good for movies and science simulations.
I think AI RT could do just as gooder job as hardware RT.

The arrival of the new Octane Render brings new dynamic instruments never before seen in any authoring renderer. The options typify lightweight volumetric field natives and deep-motion mounts for virtual reality playback with a superior shell rate. Octane Render 4 Crack at productscrack is the fastest GPU-accelerated exact renderer. Octane uses your PC’s illustration card to reproduce reasonable photos too quickly.
